2.48.00: Expanded opaque enclosure modeling, improved fuel mix estimates

This release introduces an expanded opaque enclosure schema, giving users finer control over opaque envelope assemblies. Additionally, we improve data sources for fuel mix and make a few small bug fixes.

Expanded cladding schema

We've redesigned how cladding is specified in the API, supplementing the simplified approach to a more detailed and customizable schema:

Introduced per-assembly customization of service life, reuse percentages, and material specifications
Added display names for cladding descriptions to improve readability in outputs
Added full descriptions readouts for individual cladding assemblies in the response object
Aliased
r_value
to
insulating_value
to support both imperial (R-Value) and metric (RSI) insulation measurements
Added
carbon_intensities.cladding_descriptions
to the response object, containing complete envelope details

The original simplified schema remains available for backward compatibility.

Improvements to on-site combustion data sources

We've refactored how we handle on-site energy use from fossil fuel combustion:

Simplified background data across geographies to create more consistent results
Laid groundwork for future integration with OEDI data to increase resolution of energy-related estimates
This is the first step in a longer journey toward more precise regional energy modeling

Bug fixes

We've addressed several issues with project PDF reports:

Renamed "operational energy" for greater clarity
Fixed B6 emissions appearing when energy use was excluded from calculations
Corrected structure visualization when structure was excluded
Fixed errors in stored carbon reporting

Additionally, addressed a bug affecting some reuse projects where A5.2 emissions were still being calculated when that subphase phase was toggled off.
